Youtube is riding a bicycle.
Youtube gets sick of the sticks getting caught up in its wheels.
Youtube removes the sticks.
If you adblock youtube, you just cost them money. Dead weight. How can people be so confused about how youtube works? It's a platform to sell ad-space to advertisers. If you are not viewing ads (or paying premium) you are just a stick in the wheels of the platform.
Its like sneaking into the backdoor of a buffet, eating for free, then telling the place they are going to fail when they lock the door. Even worse, you didn't even know you were using the backdoor, you thought it was the front.
